SIGNAL AND ILLTJ'IVIINATUR liCllEt AUTOMOBILE RADIATOR INDICATOR.

Application filed August 9, 1921.

To all whom it may concern:

Be it known that I, HARRY ALFRED TUGKEY, a citizen of the United States, residing at the city and county of San Fran cisco and State of California, have invented. certain new and useful Improvements in Signals and llluminators for Automobile Radiator Indicators, of which the followinn; is a specification.

Devices for indicating; the temperature of the water in a motor vehicle cooling system, particularly that type of device associated with the radiator filler cap, are

plainly readable during the day, but at night without the aid of a portable lamp a vehicle operator is unable to read the temperature of the water in the coolii system.

To maintain the successful and economical operation of a motor vehicle, it has been found necessary to maintain the motor temperature approximating a certain degree during day driving as well as night driving, and. it is the object of the present invention to provide a means associated with the temperature indicator enabling the reading of the indicating element thereof in the dark.

Another object of this invention is to utilize the present form of universally used. in dicatinp; device, and to provide a simple attachmentadapted for easy application. thereto, at comparatively little cost, and preferably by dispensing with the rear plate associated with the indicator frame.

A further object is to provide in connec tion with the present invention. a signal for intersecting tratfic i. e. traffic traveling across the path. of the vehicle by providing illuminated signals in color one facing; in each direction at the foward end of the vehicle indicating to cross traffic by lights whether the equipped vehicle will. proceed or whether the cross traffic vehicle shall proceed.

With the above mentioned and other ob jects in view, the invention consists in. the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings, and set forth in the claims hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be re sorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Serial No. 491,052.

To more fully comprehend the invention reference is directed to the aocompanyin." drawings wherein a Figure 1 is a view in side elevation of. the I'Jreferred embodiment of my invention.

F gure 2 is a vertical central section disclosing the preferred embodiment of my invention.

Figure 3 is a transverse broken sectional view through the lamp chamber.

In the drawing wherein lll'iGClllItlCtGlS of refereiice designate corresponding parts, 1 indicates the metallic attaching portion of a radiator cap mounting the exterior finishing portion 2, both of which are provided with the aligned stem receiving openings 3 into and through which projects the threaded stem 4.- of the well known type of motor temperature indicating device held in position. by a nut 5. The stem a carries a circular frame portion 6 open at its front and rear, the front, or that face disposed toward the vehicle operator being normally closed by a crystal 7 held in position by a removable ring In the form illustrated, the temperature indicating means is in the form of a closed tube 9 disposed vertically of the frame 6 with its lower end 10 protected by a shell 11 extending below the member 1. The member 9 contains a tern perature responsive fluid in the tubular portion filthereof, and in rear of said tube is a suitable indicating; disk 13 having a vertical sight opening 14 therein in'uncdiately inrear of said tube 9 and of a length substantially corresponding to that portion of the tube between the inner edges of the frame This present construction. which is of the conventional form, is that used. with certain other features closing the rear of the frame at the present time, and the preferred embodiment of applicants invention is associated therewithv in the here inafter described manner.

To the rear portion. of the frame 6 is at tached in any suitable manner by attaching means not shown the annular flanged portion 16 of a suitable lamp casing 17. The casing is provided with. an enlarged lamp chamber 18 forwardly from which extends the contracted passage 19 communicating with the rear of the sight opening 14, and in said chamber 18 is adapted for position ing an electric lamp 20 of any well known form mounted in the conventional socket 21, and adapted to be supplied with power movably mounted a colored translucent clogreen denoting the right of way sure 24 affording a signal. The member 24 over the opening 23 disposed at the side of the vehicle corresponding with the right hand of the driver is adapted to be blue or I for a vehicle approaching from that side, while the member 24 associated with the opposite openingis adapted to be red denotingthe danger or stop signal for a vehicle approaching from that side.

v Thus it will be apparent that during night driving, my present invention affords a signal for traflic at intersectin streets, and also affords a means for illuminating the tube 9 by rays passing through the sight opening 14 whereby the indicating element in the tube may be readily read by the driver,

If desired, a brace 25 may extend from the portion 4 to the socket portion 26 associated with the contact 22.

It will be apparent that the present invention is adapted for attachment to the well known forms of -moto-mete1's, now universally in use, by simply removing the back plate from the frame thereof inserting a new indicating disk formed with a sight openin extending the full length of the tube 9 an attaching my improved lamp chamber to the rear of the frame. This construction provides a mounting which is adapted to be removed with the moto-meterand radiator ters Patent of the United States is 1. In combination with an instrument for mounting on an automobile radiator and consisting of a frame, a movable indicating.

means influenced by varying indicating temperatures of water in the radiator, a dial formed with a sight opening; of means in rear of said dial for illuminating the movable indicating means enabling the reading of said means through the sight opening in the dark, the same consisting of a lump chamber having a passage for registering with the sight opening and side wall openings, a lamp within said chamber, a mounting plate associated with said chamber for detachably securing the chamber to the frame in the rear of said dial plate and translucent members associated with the said side wall openings for closing the same.

2. In combination with an instrument for mounting on an automobile radiator and consisting of a frame, a movable indicating means influenced by varying indicating temperatures of water in the radiator, a dial formed with a sight opening and a crystal. in front of the dial; of means in rear of said dial for illuminating the movable indicating means enabling the reading of said means through the sight opening in the dark, the same consisting of a metallic lamp chamber having an opening in one wall for registering with the sight opening and an opening in each side wall, a lamp in said chamber at the intersection of said openings. a red transparent member over one side wall opening, a green transparent member over the other side wall opening, and a mountin plate integral with and flaring from the walls oil said chamber for detachably securing the chamber to the frame in the rear of said dial.

3. A device for the described purpose comprising a walled lump chamber open at its sides and one end, the wall at its open end terminating in an annular attaching disk integral therewith and radiating from said open end for attaching to the rear of a radiator thermometer frame to horizontally dispose said lamp chamber relatively thereto, said chamber side wall openings adapted for closing by translucent members and a lamp within said chamber.

In testimony whereof I have signed my name to this specification.
